Dispersion Compensating Fibre (DCF)-YOFC

Dispersion Compensating Fibre (DCF)

YOFC dispersion compensating fibre is specially developed through proprietary PCVD-based technology. Taking advantages of PCVD process, YOFC is able to manufacture complex index-profile shapes accuratelly, therefore, to get the optimized products with the best compromise between insertion loss and residual dispersion over the compensated operating wavelength. Customized fibres with special center wavelength and dispersion are available.

Applications

Single mode fibre backbone and metropolitan area networks based on recommendation G.652
DWDM networks
SDH network
CATV
Dispersion adjustment

Characteristics

Broad band dispersion compensating of DWDM network and extremely low residual dispersion
80% - 120% slope compensation in C/L band
Low insertion loss and high negative dispersion coefficient
High figure of merit（FOM）
Low PMD
Customized encapsulation type, dimension, connector type and jumper length
Excellent splicing characteristics, spliced by one time discharge
